I just realized that "seeing all" only gives one page of notifications, so to delete all I need to repeat the clicks: select all notifications, check all, delete, agree it can't be reversed, then clear, and begin the whole thing over again, without having any idea of how many pages of notifications I need to clear. (Clicking on "more" does nothing) I've done at least 20 and they just keep coming, and this is getting old. Is there no way to select ALL in the box and clear at once, rather than having to go through this mindless clicking? And what about some kind of indication as to how many pages of stuff we're accumulating in there?
